9 days staying at Pemi's house was indeed a great experience. Location of the house is really walking distance away from big malls like Platinum, MBK and even Pratunam market (approximately 12 mins walk according to google map). There are many food stores, street foods and 7 eleven nearby as well so not to worry if you ever get hungry in the middle of the night. BTS is around 3-5 mins walk away (very easy to find, just walk straight and turn right)
Communication with host was never a challenge too, they spoke decent English & are helpful in answering any doubts posted by me & my BF.
Just take note that there are additional charge for electricity during your stay, so you may want to keep aside some money before spending all on shopping!
All in all, highly recommended!
